Greetings,
The AO-7 70-cm beacon was monitored with very strong signals during the 2009 February 28 22:52-23:14 UTC pass from FM18. The beacon was in a two-state mode that sounded a bit like RTTY in idle. The shift was about 50-Hz between the two states. The nominal zero Doppler frequency appeared to be around 435.1056-MHz and was rock-steady through the pass.
73,
